With php7.3 it start to return errcode 1 with some parallel processes. Windows even does not register these broken executions. I look via AnVir Task Manager / Log. Here I can see list of all executed commands. Possible problem in work with file handlers. unlink() can remove file, which in use by another proc_open(), but fopen() can't after this create new file. in vendor/symphony/process/Pipes/WindowsPipes.php:60 for second test fopen($file, 'xb') return null and can't create file, but file at this moment is not exists because was removed by 57 line. This is new bug. PHP <=7.2 work as expected. Test script: --------------- run command in Git's bash: command: phpunit-tests | head -2 | vendor/bin/fastest --preserve-order -v "phpunit {}" Where phpunit-tests return list of tests. Expected result: ---------------- Both tests successfully executed. AnVir Task Manager / Log / record about both executed test commands. Actual result: -------------- First test always is broken, but second successfully executed. AnVir Task Manager / Log / only 1 record about successful executed test command. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76872&edit=1
